Lovely ride. I pulled a cue sheet from the CRW's repository: a ride called "Another Side of Carlisle." A friend and I took the medium-length route: 43 miles from the Brigham's Ice Cream World HQ in Arlington and back again. Given our starting point in Cambridge, and a few "bonus" miles owing to a missed turn, the total came to about 55. I arrived home at lunchtime and then ran a slew of errands around town on my commuter. I'd estimate the day's total mileage at 62: a nice metric century.
The ride was lovely: circling around Carlisle, Concord, and Lincoln, with such points of interest as Great Brook Farm, the De Cordova sculpture garden, and the Gropius House. What a day. And those stiff breezes pushed us all the way home.
